FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 337,510, dated March 9, 1886.

Application filed June 18, 1885.

To all whom it may concern:

Be it known that I, CEPHAs MANNING, of Boston, in the county of Suffolk, in the State of Massachusetts, a citizen ofthe United States, have invented a certain new and useful Improvement in Feed-Water Heaters for Locomotive and other Boilers,of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forminga part of this specification, in explaining itsnature.

The object of the invention is to provide a cheap and efficient device for heating the feed-water which is supplied locomotive and other boilers, and it comprises the arrangement in the smoke-box of the boiler of a pipe of any desired size or form, arranged to extend about the liuc-sheet of the boiler in close proximity thereto, and adapted to be passed over or under the dry-pipe, as may be desired. This arrangement of the pipe in the smokebox is such that it does not interfere with the ready access to the boiler-dues for the purpose of cleaning or repairs, while at the same time it is so arranged as to receive the heat passing from the boiler-tlues.

In the drawings, Figure 1 is a side view of a smoke-box containing my improved heater, and Fig. 2 is an end View of the same.

A represents a portion of the locomotiveboiler; c, the ilues; B, the smoke-box; C, the sheet which forms the smoke-box and exterior of the boiler; D, the dry-pipe; E, the exhaust; F, the feed-waterheating device or chamber. Its casing is represented as round or in the form of a pipe; but it may be oval, rectangular, square, or of any other desired section, so long as it has the arrangement in the smoke-box in relation to the outer plate of the smoke-box or boiler herein shown and described. Its end G is connected with a pipe, g, extending from the injector or pump or other waterforcing device,(not shown,)and its other end, G, connects with a pipe, g', entering the boiler.

In the drawings the device is shown as applied to a boiler, and I have represented the water-chamber as formed by two coils of a pipe extending about it close to the flue-plate.

In lieu of arranging the coils as represented-that is, as passing under the dry-pipen they may pass over the same.

ln operation the `feed water is forced,

Serial No. 169,023. (No model.)

caused to be circulated or moved through the smoke-box into the boiler, and is of course thereby exposed to the heat which passes from the iiues to the smoke-box.

In stationary boilers the arrangement of the .heating chamber or pipe in relation to the boiler shell and flues is substantially the same.

lt will be observedthat this construction is very simple, very cheap, and does not in any way obstruct the smoke-box or prevent easy access to the boiler.

When a pipe is used to form the heatercbamber,it may be of the size of the ordinary feed-pipe, and it may be extended around the smoke-box once, twice. or as many times as may be desirable, but I Wish it to be unde stood that I do not confine myself to the especial size, shape, or construction of this pipe or chamber within the smoke-box, so long as it is arranged in the smoke-box iu relation to the smoke-box or boiler-sheet and lines substantially as herein shown and described. I prefer, also,to arrange the joints or connections of the heating chamber or pipe with the pipes connecting the water-forcing device therewith, and connecting it with t-he boiler so that they shall come outside ofthe smoke-box,to prevent their exposure to the heat of the smoke-box, and in order that they may be easily reached for repairs, tc. n

I would state that the heater may be arranged at either end of a cylinder or other shaped boiler, so long as it shall bear the relation to the lines of the boiler and the casing of the chamber or box holdingl it herein specitied.

Having thus fully described my invention,-

I claim and desire to secure by Letters Patent of the United Statesl. A feed-water heater for locomotive and other boilers, comprising a continuous or unbroken pipe arranged in the smoke-box of the boiler in close proximity to the casing thereof, to extend about the smoke-box, and also in close proximity to the flue-sheet ofthe boiler, one end of which pipeis connected outside the smoke-box with the boiler, as specified, and the other of which is connected outside the boiler with a source of water-supply, all substantially as and for the purposes set forth.

2. The combination, in a feed-water heater IOO for locomotive and other boilers, of thesmokeboiler, all substantially as and for the pur box, the Hue-sheet of the boiler, and a feedposes specified. Water heater consisbiiw of a coil of )i )e eX- 1 1 T T tending about the innear surface of th S1moke- (JEl HAS MANB Ik G' 5 box and in close proximity to the flue-sheet Witnesses:
